            <title>[SERVER-48007] Destroy ARS in establishCursors out of line</title>
                <link>https://jira.mongodb.org/browse/SERVER-48007</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Mongos has an instance of &lt;tt&gt;AsyncRequestsSender&lt;/tt&gt; in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/71a01bc43a26ec328657d7d9768ce11cad6f89a7/src/mongo/s/query/establish_cursors.cpp#L126-L127&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, and destroying it contributes to more than 1% of its execution time when running a read-only workload (YCSB 100% read).&lt;/p&gt;

&lt;p&gt;We can move the destruction off of the critical path and potentially avoid the performance penalty.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-48007&quot; title=&quot;Destroy ARS in establishCursors out of line&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-48007&quot;&gt;&lt;del&gt;SERVER-48007&lt;/del&gt;&lt;/a&gt; Destroy ARS in establishCursors out of line&lt;/p&gt;

&lt;p&gt;This commit delegates the destruction of the ARS instance in MultiStatementTransactionRequestsSender&lt;br/&gt;
to the opCtx baton to potentially move the cost off of the critical path.&lt;br/&gt;
